KINETICS OF NITROSE GAS OXIDATION BY NITRIC AND SULFURIC-ACID MIXTURES

The process of nitrogen monoxide oxidation by sulfuric and nitric acid mixtures has been studied under laboratory and model conditions at a total pressure of up to 0.56 MPa, temperature of 293-353 K, and variou s nitrose gas compositions. The degree of nitric acid utilization as a n oxidizing agent and the influence of the amount of sulfuric acid on its expenditure have been estimated. To design a bubbling apparatus em pirical equations ate given which allow calculation of the degrees of liquid-phase NO conversion, attainment of equilibrium conditions, and nitric acid utilization.
